Macomber (Summer on Blossom Street ) delves into a Seattle widower's pursuit of love in her hopeful latest. Hannah Everett dies at 36 of ovarian cancer, leaving behind a letter for her pediatrician husband, Michael Everett, to be opened on the first-year anniversary of her death. In it, she suggests he consider one of three women as his next wife: her cousin, chef Winter Adams; Leanne Lancaster, Hannah's divorced oncology nurse; and Macy Roth, a ditzy, animal-loving artist. As Macomber reveals each woman and how they react to Michael's sometimes halfhearted pursuit, the strongest personality is Macy, so it shouldn't be surprising where things head. Macomber's tale of getting on with life is charming enough, though Hannah's cancer battle is glossed over, and the conceit of Michael considering marriage so soon is a little unrealistic. (May)
